>>The University of Michigan played a
very substantial role in the early research that was used to design crash dummies
but those crash dummies are 50 years old. The population has changed very substantially
and what we’re doing is taking amazing data about human bodies collected by very sophisticated medical
imaging from real crash subjects. So we’ve taken that medical data, that
imaging data, and we’re providing it to automotive engineers so that they
have the tools and the information that they need to make safer cars.>>Some of the dummies that are in use today
were developed in the 70’s and early 80’s. And back then what it meant to be a
50th percentile male is much different than what it means to be a 50th
percentile male in the year 2017. So what we’ve tried to do is we’ve tried
to scale things up, supersize the dummies if you will, to be more representative
of the population. And as the population ages and as the
population grows, we want to make sure that the vehicles take that into consideration
when they’re designing their safety systems.>>So the 3 dummies that are there
are 1 is a new dummy in development, which is meant to represent an elderly female. In addition to being female and
older, is older a bit heavier to represent a more you know
sort of current population. In the center is a heavy set obese male.>>For obese drivers, since you have
a lot more body mass in the top, you also tend to submarine underneath. And as you submarine, you can develop a lot
of lower extremity injuries that may keep you out of work longer and take
longer to recover from.>>The dummy on the left is the one that’s meant to represent what’s called the 50th
percentile male that is currently used as the standard that’s meant to
represent but he’s way too thin to be an average male these days. They couldn’t redesign the dummies
because they didn’t have the information about the entire population and that’s what
we’re able to provide at ICAM at the University of Michigan is that through data
collected at the University of Michigan and with our academic collaboration and
collaborators from around the world, we’re able to gather, to process
this information and provide insights that can help these automotive engineers
and manufacturers make safer cars. [ Music ]
